She said: “They have given so much to the public, we were all very much involved with their wedding but there are some things that they just like to keep to themselves.”

“The news of the dog was something they wanted to keep private anyway, it’s very much their family life.”

She added: “There were some reports in early September that the name of the dog was ‘Oz’ - which was obviously wrong - and so yesterday the subject came up because someone had referred to Oz and they responded.”

Christina also noted: “I don’t think it’s a fact of them not wanting to tell anyone, I just don’t think they feel the need.”
